WAI Standards Compliance

The site has been built so that it meets as many accessibility checkpoints for A and AA compliance as defined by W3C’s Web Content Accessibility Guidelines – versions 1.0 and 2.0 – as is possible. There are some areas of the site where this has not been quite possible, but we don’t think that these are significant enough to cause anyone who requires a AA compliant browser experience to be significantly affected.
